you need two copies of keyclone to handle this

just install it on your main computer and start keyclone

install it on your second computer and start keyclone

setup keyclone on your second computer and activate
[X] Auto connect: [ IP of your main computer ]

if your firewall settings are correct keyclone on your second computer should auto connect to the keyclone session on your main computer.

each key you press will be sent to the active computer and via LAN to the other keyclone session which will broadcast the key to the wow sessions which are on your second computer.

that's it
